As you "order" free digital photos to download, you will be asked to register a credit card when checking out. You won't be charged for digital downloads—only for prints that you order. However, registering a credit card is a required step in the process with PhotoShelter, our archive gallery provider. PhotoShelter is a robust site primarily designed for commercial photographers, and provides Harker with valuable tools and customized password-protected access for our community at a minimal cost, so we hope you understand this small inconvenience. We appreciate your patience with this extra step!
